Abstract: PURPOSE:To suppress the reduction of speed due to process dispersion by using load MOSFETs of same conductive type as the collector load of a differential transistor which receives a signal of ECL level to be supplied to the gate of an amplification MOSFET in a level conversion circuit. CONSTITUTION:An amplifier LVA for level conversion is comprised of a unit ECL circuit, and P-channel load MOSFETs Q9 and Q10 are provided at the collectors of the differential transistors T6, T7.
